Additive Manufacturing of Oxide Dispersion Strengthened Alloys via Laser Powder Bed Fusion

Creator:: Ghayoor Baghbani, Seyyed Milad
Abstract:: Having a series of excellent properties, the oxide dispersion-strengthened (ODS) steels provide promising solutions for the challenges of structural materials in nuclear energy, especially the development of future advanced nuclear fission and even fusion reactors. The current manufacturing route for ODS alloys includes mechanical alloying (MA) of master alloys or...

Transition Metal Oxides for Aqueous Electrochemical Energy Storage

Creator:: Jiang, Heng
Abstract:: In the 21st century, environmental deterioration is now an indisputable fact. Reliable and economically viable electricity systems based on renewable sources are urgently needed to replace the environmentally detrimental fossil fuels. The feasibility of incorporating renewable-but-intermittent solar and wind energy heavily depends on the development of cost-effective and safe technologies,...

Catalytic chemical vapor deposition synthesis of carbon nanotubes from methane on SiO supported Fe and Fe−Ni catalysts

Creator:: Nakagawa, Ayako
Abstract:: Influences of operating conditions on the production of carbon nanotubes (CNTs) were studied using Fe and Fe-Ni bimetallic catalysts supported on silicon monoxide (SiO). The catalysts were prepared in three steps: (1) impregnation of SiO powders with ferric nitride or combinations of ferric and nickel nitrides, (2) oxidation of nitrides...

A novel lattice Boltzmann method for treatment of multicomponent convection, diffusion, and reaction phenomena in multiphase systems

Creator:: Parker, James Muirhead
Abstract:: In this work, a multicomponent lattice Boltzmann model is developed for the simulation of multiphase mixing, reactions, and separations processes. This model is unique in that diffusive mass transfer of a component in the model is driven by gradients of chemical potential. This fundamentally correct description of diffusion accurately captures...

Organic-solvent resistant ultrafiltration and nanofiltration membrane modules for separation and purification of nanoparticles

Creator:: Kim, Taehyeong
Abstract:: The intriguing size- and shape dependent properties of nanoparticles have garnered recent attention in many science and engineering areas. When the particle size is in the nanometer size range, the material exhibits very different properties such as surface plasmon resonance (of gold nanoparticles) and superparamagnetism (of iron oxide nanoparticles). The...

Method development for characterizing the hydrophobicity of engineered nanoparticles

Creator:: Lee, Fang Yu
Abstract:: Characterizing the hydrophobicity of nanoparticles can help us understand their fate and transport in the environment, as well as how nanoparticles may interact with biological systems. However, contact angle and partition coefficient have limitations in measuring the hydrophobicity of nanoparticles, thus promising methods to measuring the hydrophobicity of nanoparticles are...

Femtosecond Stimulated Raman Studies of Excited State Structural Events

Creator:: Tang, Longteng
Abstract:: Femtosecond stimulated Raman spectroscopy (FSRS) is an ultrafast vibrational technique which allows rapid collection of Raman spectra with simultaneously high temporal and spectral resolution. With the recent development of FSRS methodology, three FSRS techniques (conventional, tunable, and anti-Stokes) have been implemented in our laboratory to dissect the excited state structural...
